Abstract
The invention provides a disc-shaped workpiece frock clamp, which comprises a four-shaft connecting plate, rapid clamping mechanisms, a dividing plate, a belt bearing pressing disc, a radial centering bearing and precision bolts, wherein the four-shaft connecting plate is connected with a machine tool; a through hole is formed at the central position of the four-shaft connecting plate; the four-shaft connecting plate is connected with a central shaft through a screw; two rapid clamping mechanisms are positioned on both sides of the four-shaft connecting plate respectively, and are provided with transverse perforation holes along the horizontal direction; the precision bolts are inserted into the transverse perforation holes for fixing the dividing plate along the radial direction; the dividing plate is arranged on the four-shaft connecting plate; the central shaft passes through the dividing plate; the dividing plate and the four-shaft connecting plate are in relatively rotating sate under the action of the radial centering bearing; the dividing plate is used for bearing a disc-shape workpiece; and the disc-shape workpiece is fixed on the entire frock clamp by positioning with the central shaft and pressing with the belt bearing pressing disc.
Description
Technical field
The present invention relates to a kind of frock clamp, especially be applicable on Digit Control Machine Tool the frock clamp for discoid workpiece.Belong to field of machining on technical field.
Background technology
A kind of workpiece of plate-like comprises equally distributed six through holes on centre bore and circumferencial direction, and these six through holes also are 10 ° of angles with the centre bore horizontal plane, allow positive and negative 0.1 ° of deviation.The side that through hole makes progress forms the countersunk head taper hole.When the such workpiece of processing, usually adopt vertical precision drilling machine to add the Special indexing boring grab, namely by the skewback of 10 ° is set between workpiece and support, and keep through hole to be vertical angle, more vertically moved by precision drilling machine, and then get out through hole on workpiece.After completing a through hole, runing rest is adjusted to another lead to the hole site, again by tight drilling machine vertical drilling, until six through holes machine.But in process, because skewback is artificial the adjusting, workpiece 10 ± 0.1 degree angle orientation faces can't guarantee unanimously, cause in process the lathe depth dimensions uncontrollable, can not guarantee the dimensional accuracy of all the other hole locations, percent defective is higher, can't produce in batches.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can guarantee firm clamping force for plate-like workpiece, carry high-precision frock clamp.
The object of the invention is achieved through the following technical solutions:
A kind of disc-shaped workpiece frock clamp, be applicable to plate-like workpiece is carried out clamping, comprise that the four axle connecting plates, quick clamping mechanism, index dial, the tape spool that are connected with lathe hold compression plate and radial centering bearing and accurate latch, wherein, four axle connecting plate center positions are provided with through hole, have been connected by screw a central shaft; Quick clamping mechanism comprises two, lays respectively at the both sides of four axle connecting plates, also is provided with cross-perforating along horizontal direction on quick clamping mechanism, is used for inserting accurate latch with from the radial direction fixed indexing plate; Index dial is arranged on four axle connecting plates, and described central shaft passes index dial, and makes index dial and four axle connecting plates be the state of relatively rotating by the radial centering bearing; Be used for the carrying plate-like workpiece on index dial, adopt the central shaft location and hold compression plate by tape spool to compress, and plate-like workpiece is fixed on whole frock clamp.
Preferably, also be provided with vertical perforation along vertical direction on quick clamping mechanism, be used for insert screw with from the axial direction fixed indexing plate.
Preferably, described Digit Control Machine Tool carries four axles programming location, four axle connecting plates by default adjustment for being inclined relative to horizontal 10 °.
Beneficial effect of the present invention is mainly reflected in: because the four axle connecting plates here remain 10 ° of inclinations angle, guaranteed that 10 ± 0.1 degree tolerances are consistent, countersunk head taper hole depth dimensions is under control, the dimensional accuracy of hole circle heart position degree conforms with drawing requirement, guarantee product quality, realized batch production.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1 is the schematic diagram of frock clamp of the present invention;
Fig. 2 is the top view of this frock clamp.
The specific embodiment
See also Fig. 1 to Fig. 2, the invention provides a kind of disc-shaped workpiece frock clamp, be applicable to specific discoid workpiece 1 is carried out clamping, and then do deep processing by Digit Control Machine Tool, deep processing is mainly six through holes on circumferencial direction, and these six through holes are the countersunk head taper, and are 10 ° of angles with the centre bore horizontal plane.
This frock clamp comprises that the four axle connecting plates 2, quick clamping mechanism 3, index dial 4, the tape spool that are connected with lathe hold compression plate 5 and radial centering bearing 6 and accurate latch 7.
Wherein, four axle connecting plate 2 center positions are provided with through hole, have been connected by screw a central shaft.
This index dial 4 is arranged on four axle connecting plates 2, and described central shaft passes index dial 4, and makes index dial 4 and four axle connecting plates 2 be the state of relatively rotating by radial centering bearing 6.
Be used for the carrying plate-like workpiece on index dial 4, adopt the central shaft location and hold compression plate 5 by tape spool to compress, and plate-like workpiece 1 is fixed on whole frock clamp, and then accept deep processing.
during use, the user is placed on plate-like workpiece 1 on index dial 4, holding compression plate 5 by tape spool compresses, then by rotating index dial 4, be adjusted to the position that needs perforation, insert vertical perforation 32 of quick clamping mechanism 3 from axial direction fixed indexing plate 4 with screw respectively, insert cross-perforating 31 from radial direction fixed indexing plate 4 with accurate latch 7, thereby make whole firm being fixed on frock clamp of plate-like workpiece 1, at this moment, the user carries four axle programmings by numerical control machine for processing and locates, can regulate 10 ° of angles that four axle connecting plates 2 are needs, and keep immobilizing.Like this, plate-like workpiece 1 is the angle of inclination by the frock clamp clamping, can and then carry out the through hole deep processing by Digit Control Machine Tool.
After completing a through hole, the user only need to unscrew accurate latch 7, index dial 4 can be rotated to the greatest extent, until reach another through hole Working position, then again tighten tight latch 7 fixing can so that the processing operation of next through hole, so until complete six through holes, reach the process of plate-like workpiece 1.
Because the four axle connecting plates 2 here remain 10 ° of inclinations angle, guaranteed that 10 ± 0.1 degree tolerances are consistent, countersunk head taper hole depth dimensions is under control, and the dimensional accuracy of hole circle heart position degree conforms with drawing requirement, has guaranteed product quality, has realized batch production.
